| Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text UNANALYZED CONDITION DUE TO POTENTIAL FLOODING VIA CONDENSATE DRAIN LINES
"USAR Section 2.7.1.2, River Stage and Flow, states flooding protection against the 1,014 foot flood in the auxiliary building is provided by removable flood barriers and sandbagging. When required, these flood barriers are installed in openings leading to safety related equipment on the 1,007 foot and 1,011 foot floor elevations.
"It has been identified that the condensation drains from the switchgear room's air handling units VA-87 and VA-88 (located in the auxiliary building), and the upper electrical penetration room's air handling units VA-85 and VA-86 (located in the auxiliary building), have no isolation valves or check valves to prevent backflow from the drain line's discharge in the turbine building basement. This means that flooding of the turbine building above approximately the 1011 foot elevation (floor level of the switchgear rooms) would result in water back-flowing via the drain lines into the switchgear rooms.
"River level is currently at the 999' 6" elevation and stable. Procedure changes are currently being developed to block the affected drain lines."
River level has never reached the 1011 foot elevation at the facility.
The licensee has notified the NRC Resident Inspector.
* * * RETRACTION FROM ERICK MATZKE TO ERIC SIMPSON AT 1307 EST ON 11/30/10 * * *
"A further evaluation of the reported flooding issue determined that the flow into the switchgear rooms would be insufficient to affect the operability of safety related equipment in the auxiliary building; therefore, the incident could not have prevented fulfillment of a safety function nor could it have caused the inoperability of independent trains of safety related equipment. The situation does not constitute an unanalyzed condition. Therefore, this event is being retracted."
The NRC Resident Inspector has been notified.

| Event Text AGREEMENT STATE REPORT - VEHICLE TRANSPORTING WELL LOGGING SOURCES INVOLVED IN ACCIDENT WITH FATALITY
The Texas Department of Health, Radiation Branch, received notification from the licensee that their truck, transporting well logging sources, was involved in a rollover accident in which the driver was killed. During the accident, the overpack carrying the sources was torn loose from the vehicle but remained intact. The overpack did sustain some damage but the source boxes appear to be intact and accounted for. A U.S. Border Patrol officer was on scene and performed surveys of the overpack and surrounding area and did not detect any abnormal background readings. The sources are currently under the control of the Texas Department of Public Safety officers (Texas State Troopers) at the scene awaiting recovery and transport by the licensee.
Due to the nature of the accident, all paperwork pertaining to the sources is scattered around the accident scene. Paperwork recovered at the scene indicate that the truck was carrying Iridium-192, Scandium-46 and Antimony-124 with total activity of all packages at approximately 726 mCi.
The accident occurred 4 miles outside of Encinal, TX on State Highway 44.
* * * UPDATE AT 1708 EST ON 11/26/10 FROM KAREN BLANCHARD TO S. SANDIN * * *
The licensee has arrived on-scene, confirmed that there was no release of radioactive material and taken possession of the following packages containing 240 mCi Iridium-192, 160 mCi Scandium-46 and 320 mCi Antimony-124 for return to their Alice, TX office.
Notified R4DO (Andrews) and FSME (Piccone).

The State of Texas provided the following information via e-mail:
"It was determined after all information was collected that the incident does not meet any reporting requirement.
"The Agency [Texas Department of Health] is requesting that this event be retracted."

| Event Text LOSS OF POWER TO INSTRUMENTATION IN THE OPERATING UNITS OF THE FEED MATERIALS BUILDING
"Description of the Event: This report is performed pursuant to 10 CFR 40.60(b)(2) reporting requirements.
"On Tuesday, November 30, 2010, at approximately 0500, the failure of F-Substation caused a loss of instrumentation in operating units in the Feed Materials Building. At 0505, various weight, temperature and pressure indications were not available.
"Due to the loss of power to a load cell component, the UF6 Vaporizer weight exceeded the administrative limit. During the power loss the vessel's weight measurement was not available to the operator.
"At 0538, power was restored and instrumentation readings returned to normal. The loss of the Vaporizer weight control did not have any safety consequences.
"Isotope, Quantities and Chemical Form: No material release.
"Personnel Radiation Exposure Date (if applicable): No additional exposure to radiation or radioactive materials."
The licensee will inform the NRC Region II Office.
* * * RETRACTION FROM MICHAEL GREENO TO JOE O'HARA AT 1659 ON 12/20/10 * * *
"On December 1, 2010, Honeywell Metropolis Works made notification of Event #46444 to the NRC Operations Center. This November 30, 2010 incident occurred due to the loss of power to a load cell component. During the power loss the weight measurement was not available to the operator, and the UF6 Vaporizer weight exceeded the administrative limit.
"This twenty-four hour report was made following 10 CFR 40.60(b)(2) reporting requirements:
"Each licensee shall notify the NRC within 24 hours after the discovery of any of the following events involving licensed material: ...
"(2) An event in which equipment is disabled or fails to function as designed when:
(i) The equipment is required by regulation or license condition to prevent releases exceeding regulatory limits, to prevent exposures to radiation and radioactive materials exceeding regulatory limits, or to mitigate the consequences of an accident;
(ii) The equipment is required to be available and operable when it is disabled or fails to function; and
(iii) No redundant equipment is available and operable to perform the required safety function.
"As determined by Honeywell's safety analysis, potential UF6 release may occur due to failure to control process resulting in process vessel failure. UF6 Vaporizer load cells, which are identified in the safety analysis as a safety feature to control the total weight in this vessel, were not operable during the incident. However, load cells are not the only component designed to perform the equivalent safety function - to prevent UF6 Vaporizer failure. Thus, UF6 Vaporizer failure due to over-pressurization is prevented by the existing relief system which is designed to relieve at a pressure below the maximum allowable working pressure. This Vaporizer relief system was available and operable during the event.
"As a result of these additional considerations, Honeywell determined that the redundant equipment (Vaporizer relief system) was available and operable to perform the required safety function (Vaporizer failure prevention), and therefore the initially reported incident (# 46444) does not meet the reporting requirement (iii). Since this incident does not constitute a reportable event, Honeywell requests to withdraw its event notification #46444."
